🙈🤐 隐 hidden + 瞒 deceive — and 瞒 carries the 目 eye radical: keep truth from the eyes
隐瞒 stacks 隐 (conceal) with 瞒 (deceive), whose 目 eye component marks it as hiding something from sight. Together they mean covering up a truth, often a taboo one, so others never see it.
瞒 — eye radical 目 + 㒼 (phonetic)
A semantic-phonetic compound. The 目 'eye' radical hints at the meaning, since deceiving someone often involves covering their eyes or vision. The right side 㒼 supplies the sound. The character came to mean 'to hide the truth' or 'deceive,' extending from the idea of obscured sight.
